Tone Generator Control with light using IC 555

This the Tone Generator circuit that interesting because of can control the sound has with the light. By use the integrated circuit NE555 be pillar equipment , which perform produce sound frequency in model Astable Multi vibrator or pulse generator. And use 25 ohm small-sized loudspeakers. For the equipment detects the light. I uses LDR because of be usable good easy and economize with. For tone sound use can fine C1 get. by many values , make the low voice but when the value is a little make tall sound goes up. The detail is other see in the circuit better.

Light to Sound Wave Receiver using IC 741

This be Light Wave Receiver circuit , perform take sound signal from the light by modify from the light into pieces hear at a loudspeaker. By the circuit uses LM741 , be IC op-amp the multi-purpose IC. It use for enlarge sound signal , change the way Photo transistor into pieces give hear loudspeaker way well.

Light to Frequency Converter TSL220

A large area photodiode and current to frequency converter combined in a clear plastic 8-pin DIL package. The output is a pulse train whose frequency is directly proportional to the light intensity. The output is CMOS compatible (use a 3k3 pulldown resistor to drive LS TTL) and the frequency can be measured by pulse counting, period timing or integration techniques. The photodiode has a wide dynamic range, high sensitivity and high noise immunity. The output frequency range is determined by a capacitor in the range 10pf to 100pf, which permits the output frequency to fall within some suitable range for any given light intensity.
